ROTARY MOTOR.

To all whom it may concern: I

Be it known that Ij-'=ELMER E. HAUER, a citizen of the Unitedfstates, residin at Springfield, in the county of Clark and I of Ohio, have invented certain newand use ful Improvements in Rota v which the following is a speci cation, refen once being had therein to the accompanying drawings. Q

My invention relates to rotary motors and more particularly to a motor' for driving tube cleaners adapted to travel through-a tube with the cleaner, although it maybe used for other urposes.

The object of a compact, efficient anddurable motor,v an i to that end I have devised a motor having a stationary shaft With bearings-extending on opposite sides of the rotary motor mem-' ber arranged to both carryand take theendthrust of said member, and means are provided for efficient lubrication With these and other objectsiin viewmy invention consists of the oonstruotionsandcombinations hereinafter described and set forth in the claims.

In the accompanying drawings which form a part of this specification Figure 1: section of a rnotor embody. ing my invention and 2 is a cross-sec tion on the line 22 of Fig.

cylinder and shaft are preferablyfoimed tegral with said head. A rotary motor member 6 has a extending cylinder 7 and the forwardly extending portion is provided withia screwthreaded end 8 to attach-the tool to be driven. The bearings are mounted upon the stationary shaft and dispose onopposite sides of the rotary/ member within the respective ends of the cylinder of said memher and I preferably employ roller bearings arranged to both carry; and, telgethe end;

my invention is to provided the head,

i i 3 and cylindervv forwardly and rearwardly thrust of the rotary motor member. These bearings will now be more particularly de scribed. The front bearing has a sleeve 9 pressed on said shaft against a shoulder 10 and a sleeve 11 is seated within the forward 'end ofthe' cylinder 7 against a shoulder 12. Rol1ers13 arranged at an inclination to the axis ofthe. motor between the sleeves 9 and 11= are. rovided with grooves 14 into which projections 15 of the sleeve 11 extend.- The to which the rear end of the cylinder 7' is secured, and is further provided with a .flange 19 seated against the Rollers 20 arranged at an inclination to the axis of the motor between the sleeves 16- and 17v are provided with grooves 21 into which projections theshaft against the sleeve 16 vand locked by a nut 24 secures-the rear bearing in lace; and the cylinder? being screw threa ed at 18 to the sleeve 17 of the rear bearing, the rotary motor member and front hearingare held in operative position.

The motor is assernbledfby first' c bearing, inserting a bar in the opening 30 to keep the sleeve from turning; and then secure the casing to the supply head.

It will be seen that when assembled the interior of the cylinder becomes a closed chamber in which the bearings are disposed and this chamber is supplied with lubricant through an opening 31 having a screw plug 32 to close the same. The motor operates at a very high speed and it is essential that it be well lubricated and the arrangement as described affords ample means for the eflicient lubrication of the motor. To strengthen the 'shaft' 5 where it projects from the wall 3 a piece of wrought iron or steel 33 is embedded within the casting.
